Product details
Overview
PBSS4160V from Nexperia is a 60 V, 1 A NPN low VCE(sat) BISS transistor in SOT666 package, designed for high-efficiency switching in space-constrained DC-DC converters and inductive load drivers. It delivers RCE(sat) = 200–250 mΩ at IC = 1 A / IB = 100 mA, supports peak current up to 2 A, and operates with junction temperatures up to 150 °C.
For engineers reviewing the PBSS4160V datasheet, PBSS4160V pinout, PBSS4160V application, or PBSS4160V equivalent, this device is selected for low-loss switching in telecom infrastructure power rails, relay/motor drivers requiring <1 V saturation voltage, and compact LED supply line control where thermal resistance (250 K/W with 1 cm² collector pad) and footprint minimization are critical.
Technical Context
This NPN BISS (Bipolar Integrated Schottky) transistor integrates a Schottky-clamped base-emitter structure to suppress minority-carrier storage and reduce switching times-ton = 90 ns, toff = 500 ns-while maintaining high DC current gain (hFE = 100–150 at IC = 1 A). Its ultra-low VCE(sat) enables operation at elevated ambient temperatures without forced cooling.
The SOT666 package features four collector terminals (pins 1, 2, 5, 6) sharing a common internal node, reducing effective on-resistance and improving thermal dissipation over standard SOT23 variants. This layout supports >500 mW total power dissipation when mounted on FR4 with 1 cm² collector pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 60 V - Maximum safe blocking voltage across collector-emitter with base open; defines rail compatibility in 48 V telecom and industrial supplies. |
| IC | 1 A continuous - Rated DC collector current enabling direct drive of relays, buzzers, and medium-power LEDs without external heat sinking. |
| RCE(sat) | 200–250 mΩ - Equivalent on-resistance at IC = 1 A / IB = 100 mA; determines conduction loss (≤250 mW) and self-heating in steady-state operation. |
| hFE | 100–150 - DC current gain at IC = 1 A; ensures reliable saturation with modest base drive (e.g., 10 mA base current suffices for 1 A load). |
| toff | 500 ns - Turn-off time under VCC = 10 V, IC = 0.5 A, IBoff = −25 mA; supports PWM frequencies up to ~500 kHz in DC-DC switch-mode applications. |
| Tj(max) | 150 °C - Maximum junction temperature; allows operation in sealed enclosures or high-ambient environments (e.g., industrial control cabinets). |
Pinout & Package
SOT666 is a 6-pin, ultra-small flat-lead surface-mount package measuring 1.6 mm × 1.2 mm × 0.55 mm with 0.5 mm pitch. Its symmetrical layout and dual-side thermal pad access enable efficient PCB heat spreading.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6 | Collector (common) | Four parallel collector terminals reduce bond-wire inductance and package resistance; collectively support full 1 A current and enhance thermal conduction to PCB copper. |
| 3 | Base | Sole base connection; requires ≥100 mA pulsed drive for guaranteed saturation at 1 A load; compatible with 3.3 V/5 V logic-level microcontrollers via appropriate series resistor. |
| 4 | Emiter | Single emitter terminal; referenced to system ground in low-side switch configuration; forms return path for load current and defines VBE(sat) = 0.95–1.1 V at IC = 1 A. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VCE(sat) | 200–250 mV at IC = 1 A - Reduces conduction losses by >50% versus standard BCP55, enabling higher efficiency in battery-powered and thermally constrained systems. |
| High peak current capability | ICM = 2 A (1 ms pulse) - Supports surge loads like relay coil energization or motor startup without derating or external protection. |
| Optimized for low-voltage drive | VBE(on) = 0.82–0.9 V at IC = 1 A - Ensures reliable turn-on from 3.3 V GPIOs without level-shifting, simplifying interface design. |
| Enhanced thermal performance | Rth(j-a) = 250 K/W (with 1 cm² collector pad) - Enables 500 mW dissipation at ≤75 °C ambient, eliminating need for heatsinks in most embedded applications. |
Applications
| Telecom Power Rail Switching | Industrial Relay Driver |
|---|---|
|
Use Scenario: Selective powering of line cards or peripheral modules in 48 V telecom shelves using discrete high-side or low-side switches. IC Role / Device Role / Timing Role: Low-side switching transistor controlling 48 V supply to downstream circuitry; handles repetitive 1 A load steps with <500 ns off-time. Use Value: 200 mΩ RCE(sat) limits voltage drop to <200 mV and power loss to <200 mW per switch, minimizing board-level heating and improving system energy efficiency. |
Use Scenario: Driving 24 V DC electromagnetic relays in PLC I/O modules, where fast, low-loss switching prevents contact arcing and extends relay life. IC Role / Device Role / Timing Role: Saturated NPN switch providing controlled current to relay coil; leverages 2 A peak rating for inrush current handling during pull-in. Use Value: 150 hFE ensures full saturation with 6.7 mA base drive, allowing direct MCU GPIO control without buffer stages-reducing BOM count and PCB area. |
| LED Supply Line Control | Low-Voltage Motor/Buzzer Driver |
|
Use Scenario: On/off control of high-brightness LED strings in industrial status indicators or building automation panels powered from 5–12 V rails. IC Role / Device Role / Timing Role: Low-side current switch regulating LED current path; operates in linear or PWM mode with minimal VCE(sat)-induced dimming variation. Use Value: Stable 200–250 mV VCE(sat) across temperature ensures consistent LED brightness and eliminates thermal runaway risk in multi-LED arrays. |
Use Scenario: Driving small DC motors (e.g., cooling fans) or audible buzzers in medical handheld devices where size, noise, and battery life are critical. IC Role / Device Role / Timing Role: General-purpose saturated switch interfacing between low-power microcontroller and inductive load; uses integrated Schottky clamp to suppress flyback voltage spikes. Use Value: 340 ns storage time (ts) and 160 ns fall time (tf) minimize switching transition losses and audible coil whine during PWM operation at 1–20 kHz. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar low VCE(sat) NPN switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCP55,115 | VCE(sat) = 300–500 mV at IC = 0.5 A; lower IC rating (0.5 A); SOT223 package (larger, higher Rth(j-a) ≈ 120 K/W). | Less suitable for 1 A continuous loads or space-constrained layouts; requires larger PCB area and may need heatsinking above 300 mA. | Select only if legacy BOM compatibility or higher VCEO (80 V) is required; not recommended for new designs targeting efficiency or miniaturization. |
| PBSS4140V,115 | VCE(sat) = 250–300 mV at IC = 0.5 A; same SOT666 package but rated for 40 V VCEO and 0.5 A IC. | Appropriate for ≤24 V systems (e.g., automotive body electronics), but insufficient for 48 V telecom or industrial 60 V rails. | Choose when operating voltage is ≤40 V and cost sensitivity outweighs need for 60 V margin; retains identical footprint and thermal behavior. |
Compared with BCP55 and PBSS4140V, PBSS4160V uniquely combines 60 V blocking, 1 A continuous current, and sub-250 mV saturation in the smallest possible SOT666 footprint-making it optimal for next-generation compact, high-efficiency power switching where voltage headroom and thermal density are limiting factors.

FAQ
What is the maximum continuous collector current for PBSS4160V under standard PCB conditions?
The PBSS4160V is rated for 1 A continuous collector current when mounted on an FR4 PCB with a 1 cm² tin-plated copper collector pad. At ambient temperatures ≤25 °C, this allows 500 mW total power dissipation. Derating applies above 25 °C per the published power derating curve (250 K/W thermal resistance).
Can PBSS4160V be used as a direct replacement for BCP55 in existing designs?
While PBSS4160V offers superior VCE(sat) and current capability, it uses the SOT666 package versus BCP55's SOT223-making it not pin-compatible. Layout redesign is required. However, its lower saturation voltage and higher IC rating provide measurable efficiency and thermal benefits in upgraded designs.
How does the SOT666 package improve thermal performance compared to standard SOT23?
SOT666 provides four collector terminals connected to a shared internal node and a low-profile, flat-lead structure that maximizes copper contact area on PCB. With a 1 cm² collector pad, its Rth(j-a) is 250 K/W-significantly lower than typical SOT23 values (>400 K/W)-enabling higher power handling without heatsinks.
Is PBSS4160V suitable for automotive applications?
No. Per Nexperia's revision history (v.4, Dec 2022), PBSS4160V is explicitly marked as non-automotive qualified. It has not undergone AEC-Q101 stress testing or automotive-grade qualification. Use in automotive systems is unsupported and carries no warranty or reliability guarantee.
